WebFind the area with this circle area formula: Multiply Pi (3.1416) with the square of the radius (r). Area = 3.1416 x r squared. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Example: The area of a circle with a radius (r) of 3 inches is: Circle Area = 3.1416 x 3 squared.

3 Ways to Find the Area of a Square - wikiHow
WebTake an equilateral triangle (all sides are equal and all angles are 60°) and split it down the middle. The "x" side is now ½, And the "y" side is: (½) 2 + y 2 = 1 ¼ + y 2 = 1 y 2 = 1-¼ = ¾ y = √ (¾) 30 Degrees 30 ° is just 60 ° with x and y swapped, so x = √ (¾) and y = ½ And: √1/2 = √2/4 = √2√4 = √2 2 Also: √3/4 = √3√4 = √3 2 WebJan 28, 2024 · How to find the circumference of a circle Determine the radius of a circle. Substitute this value to the formula for circumference: C = 2*π*R = 2*π*14 = 87.9646 cm. You can also use it to find the area of a circle: A = π * R^2 = π * 14^2 = 615.752 cm^2. Finally, you can find the diameter – it is simply double the radius: D = 2*R = 2*14 ... how many backpacks should i have

WebHow to calculate square feet For a square or rectangular shaped room or area, measure the length and width of the area in feet. Then, multiply the length and width figures together. As an example, if your room measures 14 feet wide by 18 feet long, your calculation is 14 × 18 = 252 square feet. WebJul 3, 2024 · A = 56.72 square centimeters You can also calculate the area if a circle if you know the radius. So, if you have a radius of 4.5 inches: A = π * 4.5^2 A = 3.14 * (4.5 * 4.5) … WebIts like magic to change a circle into a square, click the button and poof there you have it!!
